The good news is that forced regens don’t have to be a recurring nuisance if drivers reduce impurities entering into the DPF at the start. A premium diesel fuel like Cenex Roadmaster XL can In number 6 it sounds like your dpf was blocked (dpf forced regen should be carried out with an oil and filter (if excesive oil degredation is shown) In number 9 Iam suprised a dealer did not chase you up for the fault (really they shouldn't have let the car go out as they o not if it's dangerous or not do they). Mazda forced dpf regeneration with wow after injectors replacement.
I have now had two times when the DPF has clogged up and the engine has lost most of its power. It feels like the turbo-charger is switched off. Either way the maximum speed of the car becomes about 60 or 65MPH. What happens if the engine is half way through a "regeneration" cycle and you come to the end of the journey - is that bad for the engine?
a oil change must be entered into the ecu diagnosticly, if the ecu thinks the oil is past its saturation level it will not regen, i got a mazda 6 recently with knackered dpf, added treatment sat on motorway 2500 rmp for 25 miles, came home told ecu oil changed done cleared codes good as new, but dealerships wrote the car off with a £1000
Ok, so here's my first post. There is a reason for joining as some of the information in www land is conflicting and difficult to navigate. Will try to keep it short. I've owned 3 Mazda 6 series and 2 Mazda 3's. The current stock is a 2009 Mazda 6 Diesel and a 2012 Mazda 3 Maxx sport. Lets 6GZOuQ.
